Auto: In automatic temperature compensation, the analyzer meas- ures the temperature using an RTD (resistance temperature device) in the sensor. The analyzer then uses the measured temperature to calculate the membrane permeability correction and oxygen solubili- ty factor.

Manual: In manual temperature compensation, the analyzer uses the temperature entered by the user to calculate the membrane perme- ability correction and oxygen solubility factor. It does NOT use the actual process temperature. Do NOT use manual temperature com- pensation unless the difference between the calibration and meas- urement temperatures is less than 2°C.

Manual temperature compensation is useful if the sensor RTD has failed and a replacement sensor is not available.

If Manual temperature compensation is selected, be sure to enter the desired temperature.
